Pests in Gardens and Landscapes

Pest identification
and confirmation—Hornworms

Tomato hornworms are likely to be the largest caterpillars you see in the vegetable garden. Their striping
pattern makes them hard to spot despite their size. Note the horn or thorn at the rear end. Large, black
droppings on the ground beneath tomato plants usually indicate the presence of hornworms. Adult moths
have a wingspan up to 5 inches.
